Dennis Tyler is not thrilled to be called to the White House for some publicity exercise. He is, however, a bit intrigued when, chasing an errant medicine ball, he finds in the bushes the murdered body of a Mexican diplomat. He helps dispose of the body in the Potomac to protect the President and then goes on the hunt for the killer. This will put him on the trail of an invention, an airplane catapult and retrieval system that could make aircraft carriers obsolete.
